Unified world champion Joshua said: "When I decided to become a professional boxer I felt the boxing market was stagnating and in need of new energy.

We have created history together and we are dedicated to keeping the UK scene in high demand for all boxers and boxing fans, but for me personally, the journey is nowhere near finished yet.

"Both Matchroom and Sky have backed me and have given me opportunity after opportunity and I will always deliver. They've worked very hard to give me a platform to showcase my skills and tell my story, so choosing to renew our deal was always a matter of when, not if.
